An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the work piece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In short, the ceramics which are used to cut, grind and polish other softer materials are known as abrasives.
Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool.
A wide variety of machines are used for grinding: Hand-cranked knife-sharpening stones (grindstones), Handheld power tools such as angle grinders and die grinders, Various kinds of expensive industrial machine tools called grinding machines, Bench grinders.
Abrasives and grindings are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications. The producs we can offer are: Cut Off Wheels, Sharpening Stones, Grinding Wheels, Abrasive Wheels & Stones, Abrasive Belts, Mounted Grinding Points etc. Looking forward to your enquiry.
Characteristics and Choice of Grinding Wheel
The grinding wheel from Grinding Wheel Supplier is the most important type of grinding tool in grinding. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, strength, bonding agent, hardness, organization, shape and size.
(1) Abrasives
Abrasive is the main component of the grinding wheel from Grinding Wheel Exporter. It has high hardness, wear resistance, heat resistance and certain toughness to withstand the cutting heat and cutting force during grinding. At the same time, it should also have sharp sharp corners for profit. Grinding metal. A summary of commonly used abrasive codes, features and application areas.
(2) Particle size
Particle size refers to the size of the abrasive particle size. The particle size is divided into two types: abrasive grains and fine powder. For abrasives with a particle size greater than 40 μm, it is called abrasive particles. The classification was carried out by a screening method, and the particle size number was expressed by the number of perforations per inch of the sieve passing through the abrasive grains.
(3) binder
A binder is a material that binds abrasive particles together to form an abrasive article.
(4) Hardness
The hardness of the grinding wheel refers to the difficulty of the abrasive grains falling off under the action of external force when the grinding wheel is working. The grinding wheel is hard, indicating that the abrasive grains are difficult to fall off; the grinding wheel is soft, indicating that the grinding wheel is easy to fall off. The hardness level of the grinding wheel is shown in Table 6.9.
(5) Organization
The organization of the grinding wheel refers to the proportional relationship between the three parts of the abrasive grains, binders and pores of the grinding wheel.
(6) Shape and size
The shape and size of the grinding wheel are determined according to the type of grinding machine, the processing method and the processing requirements of the workpiece.
